Anaxyeloidea

Anaxyelidae is a family of incense cedar wood wasps in the order Hymenoptera. It contains only one living genus, '' Syntexis'', which has only a single species, native to Western North America. Fossils of the family extend back to the Middle Jurassic, belonging to over a dozen extinct genera, with a particularly high diversity during the Early Cretaceous. ''Syntexis'' lay eggs in the sapwood of conifers, preferring recently burnt wood.
